open space atits. center. In practice these grates are disadvantageous in many respects, for example, due to the-opening in the cen ter it is impossible to place small vessels directly onthe grate and in using larger vesselsthe flamefrom the burner is deflected downwardly around the said rings so that it cannot impinge directly. against the entire under surface ofthe vessel on the stove, these rings being made of cast metal are relatively-expensive and exceedingly fragile and due to the latter objection many of them are broken in transit and many more frequently broken through accidental use.

i Still another objection to this form of grate istheifact that the outer ring fitting theflange provided therefor in the top of the stove leaves an annular spacebetween this ring and the adjacent portion of the store top-into which frequently, when the food in a vessel boils over, the food passes and lodges soiling the top of the stove which is difiicult to' 'keepfclean due to this structure and thereby'making the same unsanitary.

' Thec oloject of my present invention is to overcome these difficulties and in doing so the grate made in accordance with my in 'vention is preferably constructed of steel bars so tha't the same is substantially unbreakabla and each grate made of a plurality of bars connected approximately centrally. and each bar shaped, so as to provide two radially disposed and similarly placed .ar ns" adapted to extend across the opening in the top of the'st'ov'e and, so constructed that'the extremities rest upon the same and grate, and

Fig.9. 5' a s Referring to thedrawing and particularly 'toinai'y, this top includes a side member C which may be inclined as clearly illustrated in the drawing and centrally the top is proare reversible thereon as will be hereinafter more particularly described.

to Figs. 1 to 3 inclusive, the top of an oil or gas stove is indicated at A. As iscusvid ed with an opening defined bya shoulder D, an upright wall D and preferably a flange D; As illustrated in these figures the grate bar to which the present invention more particularly relatesis made of a plurality of steel bars or bands indicated at B, Band B. The bar B is a straight bar and the bars B and B" are bars similarly bent at 6 adjacent their central portions into corresponding angles so that when these central portions. of the bars B, B" are. connected to the central portion. of the bar B the grate includes a plurality of radially disposed arms adapted. to extendacross the burner opening in the top of the stove and .to. rest upon the same. Asillustrated :in these figures the central portions of the bars are provided with hole E adapted to receive a rivet E, although the bars may be welded or otherwise secured to one another without departing from the nature and spirit of the invention.

At its extremity the arms of each bar are cut so as to provide a shoulder F and an eX- tension F forming an angular extremity of the arm and as illustrated in Fig. 2 the grate hereinbefore described may be placed in position in the top of the stove so as to have the shoulder F fitted within the flange D with the extension F resting upon the flange D so that the top or upper surface of the grate is substantially in the same plane as the top of the stove; or as shown in Fig. 3 the grate may be reversed so that the extension F rest upon the flange D in a re versed position in order that the top of the grate may be raised an appreciable distance above the top of the stove.

Referring to Fig. 4; it will be seen that the stove top may include only the substantially vertical wall D and in such an instance, as will be understood, the arms of the grate must be made sufficiently long to permit the extensions F thereof to rest upon the top of the stove with the shoulder F extending into the opening in the top as shown in this figure or in the reversed position if so desired.

Referring to Fig. 5 it. will be seen that the bars of which the improved grate'is made,

as hereinbefore described, may be constructed from a continuous band of steel or other similar material by a punch and dies for cutting the same along the lines as indis cated to form the shoulders F and the extensions Fas well as to provide the same centrally with the rivet holes indicated at E. As. will be understood of course the bar must be reversed if but one end is formed at a time, although the dies may be so constructed in reversed positions as to simultaneously out both ends at one and. the same time. 7

Referring to Figs. 6, 7 and 8, it will be seen that theimproved grate may consist of the bars H, H V and the bars J and. J connected at their central portions by a rivet E or otherwise. The bars TH, H, are bent at corresponding anglesadjacent their central portions as are also the parts J, J so that when assembled and connected by the rivet or otherwise they form equally spaced radially disposed arms with the extremities thereof constructed in a mannerisimilar to that "hereinbefore described so asto be adapted to fit the top of gas or oil stove. In these figures the top of the stove is provided with a square opening indicated at K seen that a still greater number of bars and a correspondingly increased number of arms may be employed in the manufacture of my improved grate. In these figures the arms are indicated at M, M, N, N and O, O, the bar M and M being similarly constructed and employed in oppositely disposed positions as is also the case with the arms N, N and O, O, the bent portions of i the bars adjacent the central parts thereof being of such an extent that when the bars are connected by the rivet or rivets E the arms thereof, assume substantially equally spaced positions. In these figures of the drawing the opening in the top of the stove is indicated at L and the stove top at L and the extremities of the arms. forming the grate are constructed as hereinbefore described so' as to be adapted to fit within the upright wall defining the opening in the stove or to rest upon the top of the same as may be desired.

From the foregoing it will be understood that the grate made in accordance withthis invention is substantially unbreakable; that it does not in any way prevent the'flame from the burner impinging directly upon all partsof the bottom of a cooking vessel; that any cooking vessel irrespective of its size may a standing on'edge and connected centrally to each other, with one bar extending across the grate so as to'be supported at substantially diametrically opposite positions to relieve the strain at the point of connection between the same and the other bars which are substantially U-shaped and extend in radial directions from the point at which'the bars are connected.

A. grate for gas and oil stoves and the H lilrecomprising a plurality of bars, a riveted connection for securing thesaid bars centrallyto each other so that the same stand on edge, one of the bars extending substantially diametrically across the grate I so as to be supported at opposite positions to relieve the strain on the rivet connection point between'the bars, with the other bars bent to U-shaped form to provide arms which extend in radially disposed positions from the central rivet pointr 3. A grate for gas and oil stoves and the like comprising a-plurality of bars set on edge, one of which is .substantiallystraight and the othersbent to U-shaped form, and a rivet for connecting thecentral portions of the said bars to one another whereby radially disposed arms are formed from each bar, the substantially straight bar reaching across and adapted to be supported at diametrically opposite positions to relieve the strain at the pivotal connection between the same and the other bars.

4:. A grate bar for gas and oil stoves and the like, comprising sets of bars, each standing on edge and connected centrally to provide radially extending arms with one of the arms of each set lying substantially parallel to an oppositely disposed arm in another set.

5. A grate bar for gas and oil stoves and the like, comprising sets of U-shaped bars standing on edge and connected centrally to provide radially extending arms with the arms of one U-shaped bar lying substantially parallel to the oppositely disposed arms of another U-shaped bar.

6. A grate bar for gas and oil stoves and the like, comprising a plurality of U-shaped bars, and means for connecting the U- shaped bars centrally thereby providing radially extending arms with each of the arms of each U-shaped bar lying in a position substantially parallel to an arm of an oppositely disposed U-shaped bar.
